# Otto AI Protocol Revenue Leaders

> Otto AI Protocol Revenue Leaders is a paid API for AI agents from dataendpoints-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns a ranked list of top blockchain protocols by revenue, refreshed hourly with freshness metadata.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability otto-ai-protocol-revenue-leaders-32393716
```

Example prompt: Show me the current leaderboard of blockchain protocols ranked by revenue — I want to see which DeFi protocols are earning the most right now.

## When to prefer this

Use this endpoint when you need a quick, pre-aggregated leaderboard of protocol revenues without building your own on-chain data pipeline. Ideal for DeFi dashboards, research queries, or agent workflows that need ranked protocol revenue data on a near-real-time basis (hourly refresh). Prefer this over raw on-chain queries when speed and convenience matter more than live block-level precision.

## Known failure modes

- Payment not processed (402 response if x402 micropayment fails)
- Stale data if the hourly refresh job is delayed (check meta.generatedAt)
- Service unavailable if Railway deployment is down (503/504)
- Empty or partial data if upstream on-chain data source is temporarily unavailable

## How this service works

Returns the top revenue-generating protocols and their rankings.

## Output

A JSON object with a status field ('success'), a data payload containing the ranked list of protocols by revenue, and a meta object including generatedAt timestamp and staleness information so the agent knows how fresh the data is.
